But the numbers at Riverside-Brookfield High School were more or less anecdotal.

While officials admitted that student attendance was "below normal," they didn't provide any specific figures. One student Skolnik talked to said he figured "about half" of students attended on Feb. 2

So, Skolnik filed a Freedom of Information request to find out exactly what the numbers were. Turns out our student source was pretty darn close in his estimate.

Of the 1,580 students enrolled at RBHS as of Feb. 2, there were 727 absences — that's 46 percent of the student population. Of that number, the school said 510 of those were excused, meaning parents called to inform the school their student would not be attending.

The district also allowed students to leave early on Feb. 2 if parents called to authorize it. The school said it did not have a report on how many RBHS students left throughout the day.

Students weren't the only ones to miss school on Feb. 2.

According to school records, 19 teachers called in either sick or took personal days that day. Their classrooms were staffed with substitutes, who are paid between $18 and $35 per class period. The total cost to the district for subs on Feb. 2 was $2,060, according to the district.
